The batt don't hold the charge and they get very hot

First check voltage on your battery with a multimeter a fully charged batt should be 12.6 bolts . Disconnect the battery from the car check voltage, second tyical voltage regulator maintain voltage between 13.5 and 15.5 . 15 when cold and 13 when hot. The regulator allows higher voltage to force electrons into you batt. If batt voltage is under12volts change batt. Is your regulator does not maintain 13 or above change alternator or alt regulator. Good luck

"Will not Start?" Are you implying that the engine won't turn over or the engine turns over but will not run? Also, was the engine in question operational prior to experiencing the dead battery?
Sorry but we need some additional clarification.

It has to be the alternator.Go to autozone or some place like that and they can test it.

you will need a off-board charger to charge the chair Strege Mobility

theres a draw on batt. start pulling fuses one by one for a few days over nite and the circit will reveal its self. if you have a volt meter you can do same thing faster by conectin it between batt cable and batt (power must pass though meter)

Well, if the Batt don't hold charge then check the regulator on the bike with an Ohmmeter you can buy one at an Auto parts shop....motor running you should see 14.5 V if not then the Reg is out!!!

Hi Don!

If you wish to charge one battery at a time, the switch should be set to "off". Charger clips will connected to the batt you wish to charge hot-to-hot and cold-to-cold. If you want to charge both batts at once (not really recommended) switch set to "all".

Hope this helps.

Yes, If you have a volt meter, jump and start engine, with engine running you should have approx 13.5 to 14.2volts that would tell me that batt is getting charged when engine is running. you said new batt would not hold a charge, I would be thinking about a parasitic draw(small amount of power) that in time will drain batt. things to look for are glove box lights, under hood lights that dont turn off. one easy way too see if you have a draw is to disconnect one batt cable, now use a regular (12volt non-self powered) test light and touch one end to batt cable and the other to empty batt terminal, with no light switches on and doors closed, this test light should not light and if it does then you have a drain on batt that will kill it say overnight.

Have Kodak Easyshare V1253 with same, "high temp.," error then shutdown. Kodak batt. showed 25% charged. Charged batt 100% & temp. error went away. Batt. internal shows camera if batt. too hot. Try new batt.

ok asifulla! change brand new battery! or clean the charging pin!
