Battery wanted for charity😀😀

(1/5) > >>

I volunteer at our RSPCA and have just refurbished a pan AK-KO ride on mower we were donated (much fun and a longer story).

I need a starter battery for it and wondered if any members have a old one knocking around that is not totally goosed.

Currently it has a NP 7-12 battery but it has rubbish CCA rating so although it starts it once it doesn’t recover  fast enough to start again. Either that or it’s just duff (I am no battery expert).

That's a "back up" battery, the characteristics of which are to sit for long periods without draining and be maintained periodically with a slow and low charge.  Start cranking is not it's fortè so it's probably healthy but in the wrong application to function well.

You'd need a automotive equivalent to fit same space but supplying the cranking current needed for multiple starts.

Wondering if you've got the manual specification to give a battery id,  I've nothing suitable to offer.

K2-K6:
Difficult to be specific without details but you could try looking here https://www.tayna.co.uk/lawnmower-batteries/varta/ as you can input size in mm etc for the application.

Looks like lawnmower applications are in the 14 to 20 ah range though, but more "active" in that the one fitted is more likely to be seen in burglar alarm back up duty.

A further thought,  the link company may be worth a question to them as enquiry if they have anything suitable, like a returned unit that they'd consider for charitable donation.

I would have thought for a ride on mower likely to be in the 30A range 330cca such as the Yuasa UR1 garden battery or equivalent  little electric start mowers tend to use alarm type batteries

I think I need something around 50 CCA as it’s only a small 6.5hp engine

A used bike battery for any old bike would be fine I think
